Abstract: Most applications of the photochromic technique of flow visualization have involved elaborate or expensive equipment. A simple, inexpensive application of the technique is described applied to a study of the fluiddynamics phenomena involved in mass transfer across a liquid gas interface. Essentially the set-up requires only a stirred beaker with photochromic dye solution, several relatively inexpensive sources of illumination (no laser) and a 35mm still camera or, alternatively, a movie camera. The analysis of the trace patterns photographed as described and the association between the flow pattern observed and the expected heat and mass transfer mechanisms is discussed.
